To draw up Cargo Securing Manual of a container ship, securing arrangements of containers on the deck should be evaluated. The forces acting on containers and lashing rods should be calculated for the evaluation. Therefore, we developed the numerical program for calculating the forces under given acceleration conditions. We carried out the experiments for securing of containers on the motion platform and on a container ship using twenty-foot containers. Furthermore, we measured the stiffness of the container and the lashing rod used in the experiments, to obtain the input data for the calculation. By comparing the forces calculated by the program with those measured through the experiments, we confirmed the effectiveness of the program except in the case that tension of a lashing rod reaches almost zero caused by big acceleration.
